SEOUL--Top South Korean officials on Monday offered a public apology and vowed to delve into the death of a triathlete who had reported to government and sports bodies that she had been abused her team coach, physical therapist and colleagues.

Choi Suk-hyeon, 22, was found dead late last month, after sending a mobile chat message asking her mother to disclose the alleged crimes of people who abused her. Public outrage later erupted after media revelations that authorities didn’t quickly act though Choi had registered petitions over the alleged abuses with several government and sports bodies.

On Monday, Sports Minister Park Yang-woo told a parliamentary committee meeting that he “feels heavy responsibility” for her death and apologized to her bereaved family and the South Korean public.

Vice Sports Minister Choi Yoon-hee told the same meeting that a 20-member investigation team was launched last week to find why authorities didn’t properly respond to the athlete’s petitions and whether related sports supervisory or support bodies functioned over the case in an appropriate manner.

“We will thoroughly investigate,” the vice minister said. “We’ll sternly punish those” responsible for Choi Suk-hyeon’s death.

During the parliament’s meeting, the team coach, identified by lawmakers as Kim Kyu-bong, and two athletes accused of abusing Choi said that they had never beaten or abused her.

Choi’s cause of death was ruled a suicide. State prosecutors are separately investigating the abuse allegations she made before her death, according to the Korean Sports and Olympic Committee.

Last week, the world’s triathlon’s governing body expressed its shock over Choi’s death and asked South Korea’s local triathlon federation and Olympic committee to share information about her case.

The alleged abuses happened when Choi belonged to a team run by the local government of Gyeongju city in the southeast.

Earlier Monday, two of her ex-teammates told reporters they and Choi had been beaten and suffered verbal and other abuses by their team’s coach, a physical therapist and senior teammates. One of them said she and Choi were once forced to eat 200,000 won ($167 or 18,042 yen) worth of bread until dawn as a punishment for gaining weight.

The two women requested their names not be revealed, citing worries that media publicity would damage their private lives.

Choi, a junior bronze medalist at the 2015 Triathlon Asian Championships, was first picked in the national team in 2015, while still in high school. Her last major race was in October, when she finished the South Korean championship in 14th place.

The abusive treatment of athletes has been a deep-rooted problem in South Korea, which considers achievements in Olympics and other international sports events as a national pride. Athletes often live in dormitories, where coaches often exercise overbearing control, and they skip school from a young age in order to perform well at athletic events, leaving them with less education and career choices, which makes it harder for them to resist unjust treatment, experts say.

In recent years, South Korean female athletes, wrestlers and judo and taekwondo players accused their male coaches of sexually abusing them. Members of the country’s silver medal-winning Olympic curling team, cheered as the Garlic Girls for their hometown’s famed produce, accused their former coaches of verbal abuse and holding back prize money.
